Stucked at "Searching availability"

I have a urgent problem that I got from my provider at Checkfront (this code works perfectly directly on this Squarespace page with Iphone, but not on any PC browser or Android phone so i need someones help to fix this. 

Here is the code I put in and as it works already on Iphone/MAC i just need to know what I should do to make it work on PC/Android (if i update the page twice it works but before that it is just spinning saying

"Searching availability" 

<script type="text/javascript" src="//cfhermesii.checkfront.com/lib/interface--0.js"></script> <!-- CHECKFRONT BOOKING PLUGIN v25--> <div id="CHECKFRONT_WIDGET_01"><p id="CHECKFRONT_LOADER" style="background: url('//cfhermesii.checkfront.com/images/loader.gif') left center no-repeat; padding: 5px 5px 5px 20px">Searching Availability...</p></div> <script> new DROPLET.Widget ({ host: 'cfhermesii.checkfront.com', target: 'CHECKFRONT_WIDGET_01', item_id: '12', category_id: '4', partner_id: '14', options: 'tabs', provider: 'droplet' }).render(); </script> <noscript><a href="https://cfhermesii.checkfront.com/reserve/" style="font-size: 16px">Continue to Secure Booking System &raquo;</a></noscript>

Have you connected Checkfront support? They are more likely to be able to provide the support you need. Good luck!

Yes, I started with them, the problem is not on their side. The widget works fine, and also on squarespace in this case but only on Iphone/mac. I have checked, and for sure the problem is not on Checkfronts side. 

@Bella12345Bella can you share your url?

@jaeveedeehttps://magictromso.com/test-hermes

Just the test site for the widget itself. Looks the same on https://magictromso.com/dogsledding-lyngen-alps with another Checkfront widget, also fine on Mac/Iphone but not PC

Try looking in your site styles for Ajax and turn it off. That sometimes messes things up in these older templates. 

Thank you so much, I will test it
